Background: Patients who suffer from malignant tumors of the esophagus and esophagogastric junction have 5-year survival rates of up to 83%, something that is documented in the early stages of cancer. Too often, weight loss is an underestimated sign for patients suffering from cancer on the upper gastrointestinal tract. Weight loss is associated with different adverse outcomes. Even after tumor resection, malnutrition remains a severe problem that still affects long-term disease free survivors.

Material and methods: This study included the clinical courses of 205 patients suffering from cancer of the esophagus or the esophagogastric junction who were operated on between July 2007 and December 2009. On admission, the nutrition risk score was evaluated. Follow-up data were collected routinely. The aim of the underlying study was to show the prevalence of an elevated nutrition risk score (NRS) and to demonstrate its influence on perioperative mortality and morbidity. Furthermore, the relevance of an elevated nutrition risk score on the postoperative survival was analyzed.

Results: More than a third (35.8%) of the patients included in this study had a nutrition risk score of at least three. A preoperative elevated nutrition risk score did not have a significant influence on perioperative morbidity or on 30-days mortality rate. In patients with early tumor stage UICC stage I a/b, an elevated risk score of 3 or more had a significant influence on postoperative survival. In contrast, in advanced tumor stages an increased NRS did not have a significant negative influence on survival within both UICC II a/b and UICC IIII a/b.

Conclusions: Further studies are required to demonstrate whether a nutritional intervention can improve the survival rates of patients suffering from malignant tumors within the esophagus and in whom an operation has to be performed.
